Being able to understand what is going on in a flowchart enabled me to go onto create my own in my Electronics product. However it is not just enough to bang out any old flow chart Part of creating flow charts is developing good practice and keeping them as tidy and well designed as possible. My first Flow charts were really long as i had to repeat parts several times and wanted to find a way of condensing it down. I had a look through the Picaxe manuals which are really helpful and found I could use SUBS. This meant I can create just one set of commands and then call on it as many times I like.
